The proposed Internet of Things (IoT)-based Smart Shopping Cart aims to eliminate the time-consuming and quality issues associated with waiting in supermarket queues. It consists of RFID sensors, Arduino microcontroller, Wi-Fi module, and a mobile application. RFID tags and readers read product information, which is displayed on the mobile app. The system can be easily implemented and tested on a commercial scale, making it more competitive than other models.
